Definitions
- the invention relates to a wind turbine in the preamble of Claim 1 specified genus.
- Such wind turbines belong to the state of the art.
- the interaction of the main components is to use the flow energy of the wind Expert familiar. It is used, for example, in the German Specialist books “Wind Power Plants", Hau, Erich: Springer Verlag (1988) and (1996, 2nd edition).
- connection principle is Tower / gondola connections based on specified requirements of Bearing manufacturers almost the same. These write a regular Check the screw preload on the fastening screws to the warehouse before, so that free access to the screws must be guaranteed. This leads to that in the known wind turbines the main components required for conversion the mechanical energy of the rotor shaft into another form of energy are arranged above the tower / gondola connection in the gondola. With regard to the natural vibration behavior, however, they have one unfavorable distance to the tower clamping. This affects the dynamic bearing behavior of a system negative.
- the tower segments are connected using pre-tensioned screws, which are particularly at risk of fatigue fracture due to the unsteady wind are. Loose screws are often found, though they are designed with the greatest care. You are not a trigger consider explainable bearing and gearbox damage.
- the object of the invention is the dynamic load and natural vibration behavior to improve a wind turbine in such a way that the damages described above are minimized or excluded, that the foundation loads arising from dynamic loads especially reduced for new systems in the larger performance classes and that on existing foundations more powerful new ones Plants can be built.
- gondola and the supporting structure form a functional unit.
- main components to convert the mechanical energy into another form of energy are no longer in the gondola, but significantly closer to the Tower base arranged on the supporting structure.
- By relocating of the components out of the nacelle are inexpensive Distance to the tower clamping and lead to an improvement in Natural vibration behavior of the entire system. Offers from load-bearing behavior a cylindrical design of the supporting structure.
- the rotatable The functional unit is supported around the longitudinal axis of the tower via a Bearing, which with the supporting structure or in the known manner with the Gondola is clamped to the tower.
- the bearing is braced but with a new connection system according to EP 1 010 931. With this system, screws do not transmit forces and moments, so that screw relaxation and material fatigue do not occur. The on the known wind turbines mandatory mandatory regular Checks of the screw preload are no longer required. This leads to the hidden arrangement and maintenance-free Bracing the bearing.
- Another warehouse leads in the lower one Area of the support structure horizontal forces directly into the tower. This leads to a significant reduction in bending stress the warehouse functional unit / tower.
- the free space in the nacelle is used to extend the rotor shaft from the windward side to the leeward side.
- the large bearing distance leads to that desired favorable natural vibration behavior of the rotor shaft and Use of conventional and inexpensive bearings.
- the bearing forces are easy to master.
- the camp will be relative thick-walled block flanges, as are common in high-pressure apparatus construction and represent the state of the art, directly into the cylinder shell shrink wrapped. This leads to an optimal flow of power. All Forces are introduced directly into the tower wall via the gondola wall.
- Influences from the tower jam and tower shadow effect can be influenced by an optimization of the influencing lengths of the shaft ends due to the relatively large distance between the bearings.
- To strive towards equal inertia forces of the two rotor hubs affect the Torsional vibrations of the rotor shaft favorable.
- Loads on the rotor hub for example due to an extension the blade length doubles towards the rotor shaft to achieve transmitting performance.
- the present invention includes these including the locking devices arranged in the lower area on the supporting structure and act with a greatly reduced lever arm for tower clamping. This influences the dynamic load-bearing behavior of the entire system also positive.
- the schematic sectional view shows the invention Wind turbine with a cylindrical tower 2 and a nacelle 5.
- Support structure 10 connected torsionally and torsionally rigid.
- Gondola 5 and support structure 10 form a functional unit 11. This is rotatable about the longitudinal axis 3 of the tower with the tower 2 via a bearing 4 braced.
- the bearing is braced with a connection system according to EP 1 010 931. Screws do not transmit forces and Moments. Details of the connection are not shown.
- the end of the support structure 10 is between this and the tower 2 another camp 13 arranged. This transmits horizontal forces from the Support structure 10 directly on tower 2, the bearing 4 is subject to bending stresses relieved.
- the nacelle 5 is in the extension of the cylindrical tower construction cylindrical.
- the rotor shaft 7 extends within the Gondola 5 from the windward to the leeward side.
- the cylinder shell has two relatively thick-walled block flanges. In the rotor shaft 7 is mounted thereon. Because of an optimal flow of power the bearing forces are directly over the gondola wall into the tower wall initiated.
- the wind turbine On the windward and leeward sides, the wind turbine has a rotor hub 9 and 9 'on.
